The Argentina international joined the Red Devils in a British-record €75 million deal in August and has scored three and assisted a further four goals in his eight Premier League appearances to date.

Despite an encouraging start to life with the 20-time English champions, though, Scholes believes that the winger is one of a number of United players who needs a lift after a winless run of three matches.

“My concern is that the mood among the United players feels a bit low-key,” the former England star wrote in The Independent.

“Preparing for the broadcast of the game [Real Madrid vs Liverpool, for which Scholes was a television pundit] in Madrid this week, I watched reruns of last season and Angel Di Maria smiling broadly as he celebrated goal after goal with Cristiano Ronaldo.

“He doesn’t seem to be in the same happy mood at United. It feels downbeat among the team.”

Louis van Gaal’s side sit 10th in the Premier League table following their opening 10 games and host Crystal Palace on Saturday.
